CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the priority benefit of Korean Patent Application No. 10-2016-0121675, filed on Sep. 22, 2016, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.

BACKGROUND 1. Field

Embodiments of the disclosure relates to an air conditioner, and more particularly, to an air conditioner using an improved air discharging method.

2. Description of the Related Art

In general, an air conditioner is equipment that adjusts the temperature, humidity, airflow, distribution, etc. to conditions suitable for human activity using a refrigeration cycle. The air conditioner includes a compressor, a condenser, an evaporator, a fan, etc. as main components constituting the refrigeration cycle.

The air conditioner can be classified into a split type air conditioner in which an indoor unit and an outdoor unit are separated and installed, and a window type air conditioner in which an indoor unit and an outdoor unit are installed together in a single cabinet. The indoor unit of the split type air conditioner includes a heat exchanger to heat-exchange air inhaled to the inside of the panel, and a fan to inhale indoor air to the inside of the panel and to again discharge the inhaled air to an indoor space. The indoor unit of a conventional air conditioner has been manufactured to miniaturize the heat exchanger and to raise the RPM of the fan to thereby maximize wind speed and air flow. As a result, the discharge temperature is lowered, and the discharged air forms a narrow, long flow path to be discharged to indoor space.

When a user is directly exposed to the discharged air, the user may feel the cold and displeasure. On the other hand, when the user is not exposed to the discharged air, the user may feel the heat and displeasure.

Also, if the user increases the RPM of the fan in order to raise wind speed, noise increases. Also, a radiant air conditioner of conditioning air without using a fan requires a large panel in order to achieve the same capability as the air conditioner with the fan. Furthermore, the radiant air conditioner has a very low cooling rate, and requires high construction cost.

Hereinafter, the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

A refrigeration cycle constituting an air conditioner may be configured with a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle may perform a series of processes of compression-condensation-expansion-evaporation to heat-exchange high-temperature air with low-temperature refrigerants and then to supply low-temperature air to a room.

The compressor may compress refrigerant gas to high-temperature and high-pressure conditions, and discharge the compressed gas. The discharged refrigerant gas may enter the condenser. The condenser may condense the compressed refrigerant into a liquid state, and emit heat during the condensation process. The expansion valve may expand the high-temperature and high-pressure liquid refrigerant condensed by the condenser to a liquid-phase refrigerant of low pressure. The evaporator may heat-exchange the refrigerant with an object to be cooled using the evaporative latent heat of the refrigerant to achieve the refrigerating effect, and return the low-temperature and low-pressure refrigerant gas to the compressor. Through the refrigeration cycle, the air conditioner can adjust the air temperature of the room.

The outdoor unit of the air conditioner may include the compressor and an outdoor heat exchanger in the refrigeration cycle. The expansion valve may be disposed in any one of the indoor unit and the outdoor unit, and the indoor heat exchanger may be disposed in the indoor unit of the air conditioner.

The present disclosure relates to an air conditioner for cooling indoor space, wherein an outdoor heat exchanger serves as a condenser, and an indoor heat exchanger serves as an evaporator. Hereinafter, for convenience of description, an indoor unit including an indoor heat exchanger will be referred to as an air conditioner, and the indoor heat exchanger will be referred to as a heat exchanger.

FIGS. 1 and 2 are perspective views of an air conditioner according to an embodiment of the present disclosure. FIGS. 3 and 4 are views for describing the operation of the air conditioner according to an embodiment of the present disclosure.

Referring to FIGS. 1 to 4, an air conditioner 1 may include a housing 10 having an inlet 12 and an outlet 14, a heat exchanger 20 to exchange heat with air entering the inside of the housing 10, and a fan 30 to circulate air to the inside or outside of the housing 10.

The housing 10 may have a substantially circular cross section, and may have a cylindrical shape as a whole. However, the shape of the housing 10 is not limited to this.

The housing 10 may include a blade 16 to guide air being blown through the outlet 14. The blade 16 may be located on the outlet 14 to control the direction of air blowing through the outlet 14, and may block the outlet 14 to close the outlet 14. More specifically, the blade 16 may rotate between a guide position at which it is disposed in a direction that is parallel to the blowing direction of air, and a closing position at which it blocks blowing of air.

The fan 30 may be a cross-flow fan although not limited to this. In the current embodiment, the housing 10 and the outlet 14 may extend in a vertical direction that is the longitudinal direction, and the fan 30 which is a cross-flow fan may extend in the vertical direction in the inside of the housing 10.

The heat exchanger 20 may be disposed in the inside of the housing 10 to perform heat-exchange with air entered through the inlet 12. That is, the heat exchanger 20 may absorb or transfer heat from air entered through the inlet 12. Below the heat exchanger 20, a drain panel (not shown) may be disposed to collect water condensed in the heat exchanger 20.

The air conditioner 1 may include a flow path guide 40. The flow path guide 40 may be formed between the fan 30 and the outlet 14 to guide the flow of air. The outlet 14 may be located at one end of the flow path guide 40.

The air conditioner 1 may include a door 50. The door 50 may open or close the outlet 14 of the housing 10. The door 50 may be movable between a first position 50 a at which it opens the outlet 14, and a second position 50 b at which it closes the outlet 14. In the current embodiment, the door 50 may slide between the first position 50 a and the second positions 50 b, although the operation of the door 50 is not limited to this.

Since the housing 10 has a substantially cylindrical shape, the door 50 may also be curved. More specifically, the front surface of the housing 10 may be at least partially curved, and the door 50 may also be curved to correspond to the curved front surface of the housing 10.

The door 50 may include a door body 52, and a plurality of holes 54 formed in the door body 52. The door body 52 may be curved as described above in order to cover the outlet 14. The plurality of holes 54 may be formed in at least one portion of the door body 52. In the current embodiment, a plurality of holes 54 may be formed in the entire area of the door body 52. The plurality of holes 54 can discharge air to the outside of the housing 10 even when the door 50 is at the second position 50 b.

The door 50 may discharge heat-exchanged air flowing to the outlet 14 to the outside of the housing 10 through the plurality of holes 54. Thereby, it is possible to air-condition indoor space without transferring heat-exchanged air directly to the user.

Hereinafter, the operation of the air conditioner according to the above-described configuration will be described.

The heat-exchanged air blown by the fan 30 may be guided by the flow path guide 40 to thus be discharged to the outside of the housing 10 through the outlet 14.

In this case, since the air conditioner 1 blows heat-exchanged air to the outside of the housing 10 through the outlet 14, the air conditioner 1 can adjust indoor temperature more quickly than the case of blowing heat-exchanged air through the plurality of holes.

Next, operation in which air blown by the fan 30 is discharged to the outside of the housing 10 through the plurality of holes 54 of the door 50 will be described.

Referring to FIGS. 2 and 4, the door 50 may be located at the second position 50 b at which it closes the outlet 14. Air entered the inside of the housing 10 through the inlet 12 may exchange heat with the heat exchanger 20, and then pass through the fan 30. The heat-exchanged air blown by the fan 30 may be guided by the flow path guide 40 to thus be discharged to the outside of the housing 10 through a plurality of holes 54 formed in the door 50.

In this case, since the air conditioner 1 blows the heat-exchanged air to the outside of the housing 10 through the plurality of holes 54 of the discharge plate, the blown air may not be transferred directly to the user, thereby improving the user's feeling of satisfaction.

Hereinafter, an air conditioner according to another embodiment of the present disclosure will be described. Hereinafter, descriptions about the same configurations as those described above will be omitted.
